Less than one week after joining the White House, Anthony Scaramucci appears to be trying to oust Reince Priebus, the beleaguered chief of staff, as the civil war within the West Wing explodes riotously into public view. On Wednesday night, minutes after Politico reported on the details of Scaramucci’s financial disclosure form, the newly installed communications director appeared to target Priebus as a source of the leaks plaguing the Trump administration. “In light of the leak of my financial disclosure info which is a felony. I will be contacting the @FBI and the @JusticeDepartment #swamp @Reince45,” prompting immediate speculation that the Wall Street financier and longtime Trump cheerleader was accusing Priebus of committing a felony. (In fact, the disclosure form is a public document available upon request.) “In case there’s any ambiguity in his tweet I can confirm that Scaramucci wants the FBI to investigate Reince for leaking,” the New Yorker’sRyan Lizzatweeted.

Scaramucci deleted the message, and published another post claiming that his tweet was only “public notice to leakers that all Sr Adm officials are helping to end illegal leaks.” But in a follow-up interview on CNN’s New Day Thursday morning, Scaramucci did little to dispel the notion that he was, in fact, putting Priebus on notice. “We have a very, very good idea of who the leakers are, who the senior leakers are in the White House,” he told host Chris Cuomo, warning that “the fish stinks from the head.” The rot, he suggested, is coming from the chief of staff: “When I put out a tweet and I put Reince’s name in the tweet, [journalists] are all making the assumption that its him because journalists know who the leakers are. So if Reince wants to explain that he is not a leaker—let him do that.”

When Scaramucci’s appointment as communications director was first announced, the financier insisted that there was no bad blood between him, Spicer (who immediately resigned), and Priebus, all evidence to the contrary. Priebus, he reportedly told the communications staff, is a “personal friend” and characterized their relationship as “a little bit like brothers, where we rough each other up a little.” (People “literally laughed” when Priebus claimed they had a good relationship, one White House official told Politico’s Josh Dawsey.) By Thursday morning, however, the fraternal analogy had taken a darker turn. “Some brothers are like Cain and Abel. Other brothers can fight with each other and get along,” Scaramucci told. Cuomo. “I don’t know if this is repairable or not—that will be up to the president.”

In the Book of Genesis, Cain killed Abel. “One-hundred-fifty years ago people would have been hung for these leaks,” Scaramucci said at another point, referring to national security leaks. “They’re treasonous.”

While Scaramucci claimed on New Day that he was aware that his financial disclosure form was a publicly available document and did not constitute a “leak” (to say nothing of it being a criminal offense), the Justice Department did not hesitate to throw its weight behind the president’s powerful new adviser. “We have seen an astonishing increase in the number of leaks of classified national security information in recent months,” spokesperson Sarah Isgur Floressaid in a statement. “We agree with Anthony that these staggering number of leaks are undermining the ability of our government to function and to protect this country.”
